Explaining the prototype, co-author Muhammad Umair from Lancaster University in Britain told News18:

Knowing our emotions and how we can control them are complex skills that many people find it difficult to master. We wanted to create low-cost, simple prototypes to support understanding and engagement with real-time changes in arousal.

One of the most striking findings was that the devices helped participants started to identify emotional responses which they had been unable to beforehand, even after only two days.
